Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 13,731,965, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 13,731,965 | |
| -1 | -13,731,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,731,965.
Example:
1 x 13,731,965 = 13,731,965
and
-1 x -13,731,965 = 13,731,965
Notice both answers equal 13,731,965
With that explanation out of the way, let's continue. Next, we take the number 13,731,965 and divide it by 2:
13,731,965 ÷ 2 = 6,865,982.5
If the quotient is a whole number, then 2 and 6,865,982.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,731,965 | |
| -1 | -13,731,965 |
Now, we try dividing 13,731,965 by 3:
13,731,965 ÷ 3 = 4,577,321.6667
If the quotient is a whole number, then 3 and 4,577,321.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,731,965 | |
| -1 | -13,731,965 |
Let's try dividing by 4:
13,731,965 ÷ 4 = 3,432,991.25
If the quotient is a whole number, then 4 and 3,432,991.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,731,965 | |
| -1 | 13,731,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 11,119 | 55,595 | 144,547 | 211,261 | 722,735 | 1,056,305 | 2,746,393 | 13,731,965 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -11,119 | -55,595 | -144,547 | -211,261 | -722,735 | -1,056,305 | -2,746,393 | -13,731,965 |
